Abstract

In the pursuit of higher-energy-density lithium-ion batteries, one big challenge is the stability of high-capacity or high-voltage cathodes with electrolytes. An understanding of how different chemistries interact with high-energy cathodes is required to enable the rational design of coatings or solid electrolyte materials that offer long-term stability with the cathode. Herein, we systematically evaluated the thermodynamic stability among a broad range of solid-state chemistries with common cathodes. Our thermodynamic analyses confirmed that the strong reactivity of lithiated and delithiated cathodes greatly limits the possible choice of materials that are stable with the cathode under voltage cycling. Our computation reaffirmed previously demonstrated coating and solid electrolyte chemistries and suggested several new stable chemistries. In particular, the lithium phosphates and lithium ternary fluorides, which have high oxidation limits, are promising solid-state chemistries stable with high-voltage cathodes. Our research offers guiding principles for selecting materials with long-term stability with high-energy cathodes for next-generation lithium-ion batteries.

Computation-guided discovery of coating materials to stabilize the interface between lithium garnet solid electrolyte and high-energy cathodes for all-solid-state lithium batteries

Journal Article Nolan, Adelaide M. ; Wachsman, Eric D. ; Mo, Yifei - Energy Storage Materials

All-solid-state batteries with a lithium metal anode, enabled by lithium garnet solid electrolytes such as Li₇La₃Zr₂O₁₂ (LLZO), are a promising next-generation energy-storage technology. The further development of all-solid-state battery requires the integration of high-energy cathodes such as LiNi_1-x-yMn_xCo_yO₂ (NMC) with the garnet solid electrolyte with stable and low-resistance interfaces, which requires a coating layer to stabilize the interface during high-temperature sintering and electrochemical cycling. In order to guide the future development of interfacial coatings, we perform high-throughput thermodynamic analyses based on first-principles computation to investigate the stability of LLZO garnet and high-energy NMC cathodes with a wide range of materialsmore »« less

Dense 3D Nanoscale Electrode Batteries with a Conformal Solid Electrolyte

Technical Report Elliott, Brian J.

Using dense, 3-dimensional (3D) arrays of nanoscale cathodes and anodes offers the potential to increase the areal energy density of rechargeable batteries for electric vehicles by at least an order of magnitude. However, developing batteries with such fine-scale patterns requires the development of electrode processing methods and a conformal solid electrolyte material that pasivates the large amount of interfacial surface area in 3D electrode and that also serves as a very thin, but durable separator between the cathode and anode. 3D electrodes have a high surface area to volume ratio so stabilizing the solid surface is critical.

Utilizing Conjugated Imine Polymers to Stabilize Nanoparticle Silicon Anodes

Conference Martin, Trevor ; Rynearson, Leah ; Kuller, Mackenzie ; ...

Silicon anodes provide a compelling route towards delivering high-capacity lithium-ion batteries, however they are notoriously difficult to stabilize in conventional liquid electrolytes that are compatible with high performance cathodes. Furthermore, the drastic changes in volume that occur as silicon is lithiated and delithiated can lead to rapid cell failure and novel polymeric binders are known to help mitigate mechanical issues. We have recently developed a novel method to synthesize the conjugated polymer phenylmethylimine (polyPMI) using an imine metathesis reaction. We have demonstrated that this polymer can be used to stabilize silicon nanoparticles to produce a composite lithium-ion battery anode thatmore »« less

Stabilizing and understanding the interface between nickel-rich cathode and PEO-based electrolyte by lithium niobium oxide coating for high-performance all-solid-state batteries

Journal Article Liang, Jianneng ; Hwang, Sooyeon ; Li, Shuang ; ... - Nano Energy

The pursuit of high energy density and safe lithium ion batteries (LIBs) is the urgent goal for the development of next-generation electric vehicles (EVs). All-solid-state batteries (ASSBs) with the combination of poly(ethylene oxide) (PEO)-based solid polymer electrolyte (SPE) and Ni-rich lithium nickel manganese cobalt oxide LiNi0.8Mn0.1Co0.1O2 (NMC811) cathode are promising candidates for EVs due to their improved energy density and safety. However, the low electrochemical oxidation window of PEO-based SPE and the instability of NMC811 at the charge/discharge process seriously restrict the battery performance. Herein, a high voltage stable solid-state electrolyte layer lithium niobium oxide (LNO) is coated on themore »« less

In Situ X-ray Diffraction Studies of Cathode Materials in Lithium Batteries

Conference Yang, X Q ; Sun, X ; McBreen, J ; ...

There is an increasing interest in lithiated transition metal oxides because of their use as cathodes in lithium batteries. LiCoO{sub 2}, LiNiO{sub 2} and LiMn{sub 2}O{sub 4} are the three most widely used and studied materials, At present, although it is relative expensive and toxic, LiCoO{sub 2} is the material of choice in commercial lithium ion batteries because of its ease of manufacture, better thermal stability and cycle life. However, the potential use of lithium ion batteries with larger capacity for power tools and electric vehicles in the future will demand new cathode materials with higher energy density, lower costmore »« less
